CABLE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 571,440, dated November17, 1896 Application filed August 15, 1896. Serial No. 602,847. (Nomodel.)

To all whom, it may concern.-

Be it known that we, EYVIND LEE IIEIDEN- motor usually derives itsenergy from an overhead feeder-wire, as in ordinary trolley systems. Themotor serves to propel the car and thereby to transport the burden. Theload is slung between suspenders which extend from the car and from aguide-trolley mounted on the cableway at a defined distance from thecar. In common practice the suspenders take the form of the familiarblock and fall, the fore and aft ropes running to a winch mechanism onthe car actuated by the electric motor. Provision is made for propellingthe car and for working the winch simultaneously, or again, if there bedifferent winches for the separate falls, for working the winches inunison or independently, as may be requisite.

The invention is peculiarly fitted for transporting logs or likeunwieldy burdens over a lateral cableway to the skid, chutes, landings,

or main-track line of the. system.

In the drawings like parts have like designation throughout.

Figure 1, Sheet 1, is a side elevation view of the car, theguide-trolley, and the tackle supportinga log. Fig. l is a rear view ofthe car. Fig. 2, Sheet II, is a plan view of the car, showing the motor,propulsion-sheaves, and the winch mechanism; Fig. 3, Sheet III, aninterior side elevation, the car-body being in section.

The cableway a is supported in any suitgenerator at the skidway-stationmay conveniently serve as a source of supply for the current, whichpasses thence by feeder-wire Z2 and trolley-pole c to the motor cl,mounted on the car 6. The feeder-wire is strung along in familiarfashion in near relation to the cableway, while the pole and motor areof any usual approved pattern.

Upon the cableway a. travel the wheels f, having straps g at the axlesthereof, and a distender h, affixed to the respective axles to determinethe distance between the wheels. At one end the cross-braces i unite thecarbody with the strap of the front wheel. At the opposite end a tie-rodk with turnbuckle Z thereon unites the rear wheel and car. By shiftingthe turnbuckle the tension on the drive-belts for the car may be varied.A guide-trolley m moves along the oableway in defined position to thecar, the strap n of the trolleybein g flexibly united for such purposeto the rear end of distender h through the medium of connector 0,jointed thereto by bolt 19. The flexible relation of the trolley to thecar-sustaining wheels enables the system to pass curves of short radiusalong the cableway without risk of jumping the track.

Upon a suitable frame Awithin the car is journaled the electric motor (Zin mesh by pinion q with the gear-wheel 'r of main shaft 3. Near itsopposite end the shaft 3 loosely carries the companion sheaves 15, aboutwhich pass the d rivebelts u, extending thence overhead and front andrear to the sheaves 1) at the carrier-wheels f. Each of said Wheels fand its adjacent sheave t are rigidly united and revolve upon a commonaxle. By this provision whendrive-sheavest at the car are caused torevolve the overhead wheels fnecessarily partake of the movement, andthus the car is propelled.

Ratchet 7, affi Xed to one ofthe winches, encounters pawl 8 to prevent the barrel from unwinding.This expedient ordinarily comes into play after the winch has raised theload to suspended position and the car is being propelled to transportthe burden. At such juncture the clutch 9 on main shaft 3 is thrown offfrom pinion 2, which latter being no longer positively driven ridesloosely on shaft 3, and thus, except for pawl and ratchet 7 8, must thatthe main shaft through its clutches controls not only thepropelling-Wheels, but also 1 the winch mechanism, and at times maycompel their simultaneous action, as in effecting a flying lift of theburden.

Generally a single winch serves for raising and lowering the load. Forthis purpose the tackle consists of companion block and falls to suspendopposite ends of the log or other burden. Guide -block 10 and hookblock11 with cable 12 are carried by trolley m, while car-block 13 andhook-block 14: with cable 15 are sustained from the car. The free endsof cables 12 15 move through block 14 and pass thence to the winch.Grippinghooks 16, carried from the straps of blocks 11 14:, seize thelog and stoutly hold it in sus pended position.

The exterior or companion winch 011 counter-shaft 4 may be used at timesfor one of the lifting-cables, in which event the front an d rear fallsfor the bu rd en each has its own winder. Ordinarily the dual winchcomes into play at other occasions, being used for snaking out logs fromdifficult or remote position preparatoryto transportation. The electricmotor affords the requisite power immediately at command to aid theloggers in snaking their burdens to the traveling car.

Obviously the details can be varied according to the skill of themechanic without essential departure from the principles of theinvention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The combination with the cableway and with the traveling carsuspended therefrom, of the electric motor mounted on said car, thewinch mechanism driven by said motor, the guide block separatelysustained upon the cableway at a defined distance from the ear, thecar-block and the dual tackles extended between each block and the winchmechanism therefor, substantially as described.

2. The combination with the cableway and with the traveling carsuspended therefrom, of the electric motor mounted on said car, thecompanion winches driven by said motor, the guide-block sustained uponthe cableway at defined distance from the car, the car-block and theseparate tackles for each block and its corresponding winch,substantially as described.

3. The combination with the cableway and with the traveling carsuspended therefrom,

of the electric motor mounted on said car, the

car-propelling wheels and the winch mechanism independently driven bysaid motor, the guide-block separately sustained upon the cableway, thecarblock, and the separate tackles extended between each block and thewinch mechanism therefor, substantially as described.
